This study examined stroke risk factor profiles, management and outcomes for elderly patients with English-speaking background (ESB) and non-English-speaking background (NESB). This is an observational cohort study with both retrospective and prospective components. In total, 186 consecutive acute stroke patients aged > or =65 years admitted to our hospital were recruited over a 12-month period. Patient characteristics, stroke risk factors and management, in-hospital mortality, functional independence measurement scores before admission and at discharge, and discharge destination were recorded. On admission, NESB patients with atrial fibrillation (AF) were less likely to be taking warfarin than ESB patients (1 out of 19 with NESB vs. 19 out of 41 with ESB, p = 0.001). More NESB patients had a history of diabetes mellitus (DM) than ESB patients (41.4 vs. 10.2%, respectively; p = 0.001). However, ESB and NESB patients were comparable in terms of age, gender, preadmission functional status as well as other stroke risk factors (including smoking and alcohol drinking pattern, prevalence of hypertension and lipid disorder) and their management. In-hospital mortality was similar between ESB and NESB patients (10.2 vs. 8.6%). In conclusion, we found an association with our population of elderly NESB patients and an underutilization of warfarin for AF as well as a higher frequency of DM. Determination of the underlying reasons for such differences may be of value in the primary health care of NESB patients.
